Nvidia responds to accusations and investigations from Chinese and United States governments.

The statement comes as both US and Chinese authorities probe the lucrative global AI chip business, which NVIDIA dominates.

Nvidia’s chief security officer has published a blog post insisting that its GPUs “do not and should not have kill switches and backdoors.” It comes amid pressure from both sides of the Pacific, with some US lawmakers pushing Nvidia to grant the government backdoors to AI chips, while Chinese officials have alleged that they already exist.
